WARNING This shi contains NTR and much worse unnecessary sxual stuff and much more stuff that makes you question why sun not exploding already not even self torturing chainsaw man and rent-girlfriend touches this shi
Spoilers
As someone is going to involuntarily ask what "ntr" happens. There is no permanent ntr. The only ntr scene is with red hair fmc where she's forced to "help out" her shota spirit spirit in a fake realm sorta thing.
There could be 2 or 3 more instances of "ntr" that isn't really ntr imo since it's not permanently stealing the girl from mc, but it's with horned crow lady.
All the fmc including horn women have still not done it as of ch 181, unless you count Haniya or the shrine women but they're both one off side characters.
